问题 I have been playing with the Fabric.js library for a little while. What like about it is the ease of transforming objects and a couple more. I am wondering if there is a plugin or any way to animate Fabric elements using GSAP? 回答1: It can be done by passing the fabric objects into the GSAP const tl = new TimelineLite(); tl.staggerFromTo( [fabricObject], 1, {left: -config.width}, {left: config.width, onUpdate: () => canvas.renderAll()}, 0.4); 来源： https://stackoverflow.com/questions/46324061

问题 I am really new with GSAP and I think it is amazing. However I cannot work out how to fade in these items separately. 1st one (this is fine) for the 2nd wish to fade in at a certain time and 3rd at a certain time. JavaScript: function startFinalAnimation(){ var fa = new TimelineLite(); fa.to(finalAvatar, 2, {scale: 0.45, delay: 0, opacity: 1, transformOrigin:"-3% 8.8%"}); fa.to(finalContent, 4, {delay: 0, opacity: 1}); fa.to(logo, 5, {delay: 0, opacity: 1}); } 回答1: TimelineLite 's .to()

问题 I have a Swiper slider and a counter position like "1/10". I would like to change that current slide number (the 1) with an animation. I know how to replace the number but with this animation, it's like another story: As you can see on the gif, it's working nicely if I click moderately on my slider, but when I double-triple-or-crazy click on the next link, that totally breaks the counter, due to the clone made in this gif example. Do you know how can I do that in a better way? I made a

问题 I mean something like this. How can I obtain that result with a library like GSAP, Transit or VelocityJS? http://www.echocapital.com/ Thanks in advance :) 回答1: Dunno about GSAP and Velocity Cause all you need is a bit of CSS and some JS or jQuery, I mean you can rewrite easily the below in vanilla JS: var $gal = $("#gallery"), $img = $gal.find("> div"), n = $img.length, i = 0, t; $img.eq(i).addClass('on'); (function loop() { t = setTimeout(function(){ $img.removeClass("on").eq(i++%n).addClass

问题 So I'm working on porting an animation of clouds from css animation to a js animation using TimelineMax. however, I've always found myself problems with Timeline[Max/Lite]. This time is quite the same. I've gone over the docs, but can't seem to find the problem. is there anything i'm missing from the arguments I pass or other parts of my code. any suggestions help as this is preventing me from moving forwards. thanks! just to clarify, the animation is means to be a looped animation clouds

This is what I've done so far: Codepen . function generate(){ var $element = $("<div>", {class: "box"}); //Generate random x and y coordinates var posy = (Math.random() * ($('body').height() - $element.width())).toFixed(); var posx = (Math.random() * ($('body').width() - $element
